I don’t think it’s the ADHD. I have it but I’m very conservative on the stack. And I know many developers who don’t have ADHD, some newbie and some who code longer than 20 years and are going after the latest shiny thing.

I think it’s more of what people assume it’s a status symbol among their peers. I noticed for example, in church, that some people think the more boring is more saint and don’t like more a church with a more contemporary dynamic approach and I think the same effect applies in the software development world.
